Clavelina picta is a tunicate in the subphylum Tunicata, a sister subphylum to the Vertebrata. Humans are members of the subphylum Vertebrata. These simple-looking organisms are marine filter-feeders with a sac-like body structure. These "higher animals" are the first we've seen in the numerous trips we've made to St. John.
The bright fish is a blue chromis (Chromis cyaneus) foraging on a reef. Blue chromis are captured and sold for the aquarium trade. The reef surrounds a group of 4 rock pinnacles that extend and descend the same 50 feet above and below sea level in the British Virgin Islands. The Indians are regarded as one of the best shallow dives in the BVIs.
"The Baths", located on the island of Virgin Gorda in the British Virgin Islands, is testament to the Caribbean's volcanic and tectonic origins. The predominant rocks forming most Caribbean islands are basaltic from eruptive volcanos and these granitic rocks formed deep beneath in the Earth's mantle and have been uplifted to the surface and subsequently eroded to their present shapes. This kind of rock is found only in a few places in the Caribbean. The name The Baths refers to their origin from the batholith.
The largest boulders are about 40 feet long and they form tunnels, grottos, and tidal pools. In the image above we are standing in one of the grottos, a picturesque room called the Cathedral.
Here's a Caribbean spiny lobster (Panulirus argus) hiding in the protective recess while waiting for the sun to go down before venturing out to forage. These Caribbean lobsters are closely related to the California spiny lobster (Panulirus interruptus) common to the coastal waters off California and Baja California. They are highly prized by fishermen and divers so they rarely live more than 5 to 7 years. Lobsters are thought to live up to 50 years although there is no hard evidence that this is so.
Caribbean spiny lobsters are also under fishing pressure and are scarce in some areas. This lobster was photographed along a shallow coral reef/rocky shore. Mass migrations after winter storms have been observed where up to 50 individuals move single-file across open terrain. A common French grunt (Haemulon flavolineatum) swims by above the lobster.
We saw this brightly colored fish, one that we hadn't seen before, while snorkeling in Little Lameshur Bay on the south coast of St. John. I followed this fish around trying to get a good profile shot of the fish. This was one of about 10 shots I took that shows the bight colors. The predominantly blue with yellow tail and blue stripes is a juvenile of the Queen angelfish; filmed June 17, 2013.
The larger, predominantly green angelfish above is the adult Queen angelfish (Holacanthus ciliaris); filmed May 29, 2012. There are a number of different adult forms ranging from mostly yellow to blue to the green forms.
We saw this octopus this afternoon while snorkeling at Maho Bay on the north shore of St. John, Virgin Islands. We spotted the octopus after noticing a number of shells of the whelk, a common, and sometimes large marine snail.
Not long after we began to snorkel in Hawksnest Bay we came across this Southern stingray (Dasyatis americana). The ray was feeding as it stirred up the sandy bottom waiting to slurp up invertebrates

This former GCSF / Santa Fe rail line is now owned by Heart of Texas Railroad HOTR which recently bought out the former, financially troubled, Gulf, Colorado, & San Saba Railroad (GCSR). HOTR was still operating (leasing?)the GCSR GP15s on this line with the exeception of one, notable grass fire starting, locomotive unit which is now stranded in Brady Texas. The three GP15 units were idle in the Lometa yard (BNSF interchange) at the time of the Sunday fire.
